About mem9
Persistent memory layer for AI agents and coding assistants.
Useful for developers who want agents to remember context across sessions, tools, and machines.
mem9 offers a persistent memory layer designed to keep AI agents and coding assistants context-aware across sessions, tools, and machines. By providing a unified cloud memory backend that supports hybrid keyword and vector search out of the box, mem9 removes the overhead of duct-taping databases, vector stores, and sync scripts. Instead, developers get instant persistent storage with zero schema design, no control plane, and no complex operations. The memory follows your agent everywhere—close a tab, restart a machine, or switch devices, and your agent’s context survives thanks to durable cloud storage. With mem9 free Monthly Credits, you receive 10,000 memories and 1,000 retrieval API calls each month at no cost, making it an ideal starting point for solo developers and small projects to add long-term recall without upfront expense. The platform integrates seamlessly with popular agent runtimes like OpenClaw, Hermes Agent, Claude Code, OpenCode, Codex, and Dify, allowing you to share the same memory space across different tools through a single API key. A visual dashboard lets you review, analyze, import, and export stored memories, giving full transparency over what your agents remember. For those who prefer full control, mem9 is open source under Apache 2.0, with a Go server, TypeScript plugins, and bash hooks available for self‑hosting. The free Monthly Credits reset automatically each month, so you can rely on a predictable allowance without manual renewal. Security is built around clear operational boundaries, ensuring that persistent cloud memory enhances agent workflows without compromising data privacy. Developers looking to scale from experimenting with AI agents to production‑ready systems will appreciate that mem9’s memory layer handles the first state problem in agent systems, while an optional extension (drive9) later supports files and artifacts. With strong benchmark performance on the LoCoMo dataset—achieving a 58.84% F1 score and 71.95% LLM score—mem9 proves its ability to maintain context across long conversations, including multi‑hop reasoning, temporal reasoning, and adversarial robustness. The combination of zero‑plumbing setup, hybrid recall, and a generous allocation of mem9 free Monthly Credits accelerates development cycles, letting you focus on building smarter agents rather than wrestling with persistence infrastructure. Whether you’re building a personal AI assistant or integrating memory into a multi‑tenant workflow, mem9 delivers the durable, searchable, and shareable context that modern agent‑driven applications demand. The free tier’s monthly allowance of memories and API calls is more than enough for continuous development and testing, and the open‑source core ensures there are no lock‑in risks as your needs grow.
